Beit known thatl, VICTOR N. PERRY, a citizen'ef the United States,residing at Bn/Bielli), in the county of Erie and State of NewYork, haveinvented a new and useful Improvement in VVheel-Chocls, of which i thefollowing is a specification.

This invention relates to retarding at-.

tachments for use on the wheels of motor cars and other vehicles for thepurpose of preventincr or indicating the theft of the vehicle. he device'has a part adapted to engage the road or pavement to give warning tothe public that the vehicle is being stolen andthedevice may also beused as a traction device when applied to a drive wheel of a motorvehicle to -assist in extric'ating the vehicle from a mud hole, or froma sandy or other soft place.

In some retar'ding devices of this sort now in use a single, outwardlyprojecting spur is provided, the body of the .device embracing and.conformino' substantially to the crossfsection of the rim and tire; someother devices embrace the rim and tire and have a part which surroundsand is locked to a spoke ofthe wheel. Devices of this sort, however, arenot always reliable as, in the first case Yby deflating the tire thedevice may be turned laterally so that the spur will not engage the roadand in the second case the spoke could be cut and the device turned orremoved. The purpose of these devices may therefore be defeated.

One object of this invention is to improve retarding devices of thissort so that 'theyv may serve their intended purpose regardless of theirposition'when encircling the rim and tire of a. wheel; also to constructthe device so that it may be advantageously used as a traction deviceunder certain conditions; also to improve the construction of devices ofthis kind in other respects heren inafter specified.

In the accompanying drawings:

vFigure 1 is a fragmentary'side elevation of a vehicle wheel providedwith a wheel attachment;enibodying the invention.

Fig. 2 is a transverse sectional view of atire. and showing a face viewof the wheel attachment secured thereon.

Fig. 3 is a face view thereof, disconnected fromthe wheel. and shownpartly open.

Fig. 4 is a sectional elevation thereof on line 4--4. Fig. 3.

Fig. 5 is a face view of a slightly modified form of retarding device,applied to a wheel.

yThe wheel attachment shown in the' ac companying drawings is attachedto a wheel A ofa motor vehicle comprising the usual spokes 10, felly ll,rim and tire 13. which may be of any suitable form.

The wheel attachment shown in the drawings and embodyingthe'inventioncomprise two parts adapted to be locked to each other and having aninner sleeve or flange adapted to extend around and engage the tire,felly and rim of a wheel, and a web orn flange which extends outwardlyfrom the inner sleeve and forms aprojection or chock which to a certainextent resists the turning of the wheel.

The wheel attachment shown 1n Figs. 1 to 4 is formed of two members orparts B- B', which, in the construction shown, aresubstantiallysemi-annular and which are hinged together at one end by a pivot 0r pin14. Each member comprises a substantially semi-cylindrical sleeveportion l5 and an outwardly extending, relatively wide, semi-annularlweb 16, the sleeve portion preferably being wider than the web 16 toform an extended bearing surface on the tire and rim in any position inwhich the device may be placed on the tire and rim. The member B isprovided at the end opposite to the pivot 14 with a boss or projection17 which is adapted to be locked or secured in any suitable manner tothe corresponding adjacent end of the member B to retain the attachmentlon the wheel A, The means shown in the drawings comprise a cylinder lock18 arranged in the boss 17 and having a part 19 provided with a boltwhich is adapted to enter a boss or socket 20 in the member B. to lockthe members B B together. When the attachment is secured on the wheel A,as shown in Fig. 2, the webs 16 form a wide annular flange having acontinuous retarding edge 20a, so that the device will function properlyregardless of the position thereof on the wheel. In other words, thedevice is free to turn or roll on.v

its axis and lit will at all times have an out-` wardlv projectingportion which will resist u'Se With the device on one of its Wheels, isstolen. The circular. concentric edge '20a` together ivith thecylindrical .sleeve parts 15, make the driving ot a vehicle. vvith thedevice attached, very uns-ate. as a device having these feature notoid'vcause;- a jarring of the vehicle each'time the, art-iclnnent strikes theroad. but ivill also cause the ves hicle to roll or skid sideyvise il'driven fast and its purpose of returning the vehicle is thereforeincreased.

If desired, the pivoted ends ot' the members B I5 may be provided with acoperating tongue Q1 and groove '22, as shown in Fig. 3 to prevent theinsertion of a tool in an attempt to pry the members apart o break thepivot joint.

In Fig. 5 is shovvn a slightly modiied form ot retarding device, whichinstead of having` a cylindrical sleeve portion, is provided withmembers C C', having sleeve parts 25 which substantially conform to thecross section of the telly l1, rim 1'2 and tire 13. Vebs 26 of uniformWidth, as in the members B B', form a retarding edge 27. This modifiediorm of device is not adapted in its normal use to rotate relatively tothe Wheel, but nevertheless will prevent or indicate the theft of avehicle even if the tire is deflated and the deviceI turned around, assome portion of the edge 27 would always engage the roadway and retardthe vehicle.

Another feature of either form of the device shown iu the drawings isthat it may be used as a traction device or cleat for the drive Wheel orwheels ot' a motor vehicle.

If a drive Wheel becomes embedded in a mud hole or sandy spot and`rotates Without being able to obtain proper tractive Contact, thedevice may be applied to a driving Wheel and the broad, t 'ansveiLselydisposed web or flange vvill dig into 'the mud or sand and givesuliicient traction to extricate the vehicle.

The described construction 'provides a very strong and simple retardingdevice which will properly serve its intended purpose at all times andwhich cannot readily `be broken or removed. Moreover, the ability to useit as a traction device under certain conditions adds to its usefulness.

I claim as my invention: 1

l. In an attachment tor vehicle Wheels., the combination of two membersadapted to be'locked together to embrace the tire and rim o't a wheel,said members having outyvardly extending portions which, vvben themembers are locked together, form a substantially continuous transverseprojecting flange around the tire and rim.

Q. In an attachment for vehicle wheels, the combination ot t\vo membersadapted to be locked together to embrace the tire and rim of a Wheel.said members having inner flanges adapted to engage the tire and rim.
